Graphical Abstract

Optical Lens Fabrication

In article number 2300517, Yong Chen and co-workers introduce a continuous vat photopolymerization method for optical lens production. This approach achieves nanoscale surface roughness and microscale shape accuracy. Utilizing a zooming-focused projection system, the authors continuously modify ultraviolet mask images, allowing for controlled frustum layer stacking and the elimination of staircase aliasing. This approach offers a promising strategy for 3D printing optics without post-processing.
